Authentication is absolutely necessary to many Internet services. In a secure network communication, each side has to prove its identity to the other through some mechanisms, and correspondingly, each side should validate the other's identity to know whether he has the right. Then the access control and accounting can work on. Authentication is the basis of other secure services. The remote strong authentication technique is a powerful way to solve the secure problems under network environment.After analyzing the elements in an authentication system, the author discusses the dynamic encrypt mechanism, its security feature and realized implemental scheme, which provides the theoretical basis of dynamic authentication scheme. The author researches the remote strong authentication technologies and points out that the authentication system's security intensity depends on the elements in it and the way the elements joint together. Using theories in combinatorial math and probability, an arithmetic model that shows the relation between security intensity and the elements is set up. And this model provides the guiding principle for designing the remote strong authentication system. The author improves the S/Key authentication system based on the dynamic password authentication and makes it a more secure scheme. To overcome the limitation of pure authentication, a mechanism using smart card with digital certificate in it is brought forward. Finally a USB key based distribution system of e-shopping is listed as an example, a simpler scheme is discussed, and corresponding programs are also given.It's worthy to notice: the enlightenment from dynamic encryption mechanism improving authentication system's security, the guidance from the arithmetic model for designing strong authentication system, the scheme that based on smart card technique and PKI if safe and efficient.
